TIPPING HAZARD
Any transport on a slope greater than the
maximum security slope can be dangerous.
ELECTROMAGNETIC RADIATION DANGER
The behavior of the wheelchair while driving
may be affected by electromagnetic fields
created by transceivers such as: Citizens
band (CB) radios, walkie-talkies, fire and
police radios, cellular phones, lap-top
computers, two-way radios, and commercial
radio and television broadcast antennas.
PLEASE USE CAUTION in the presence of
these devices.
EMI can cause your chair, without warning, to:
• Release its brakes
• Move by itself
• Move in unintended directions
If any of these occur, it could result in severe injury to you or
others. EMI can damage the control system of your chair.
There is no way to know the effect on EMI if you add accessories
or modify this chair. Any change to your chair may increase the risk
of EMI. Parts from other suppliers have unknown EMI properties.
The wheelchair might disturb the operation of devices in its
environment that emit electromagnetic fields
TEMPERATURE
The temperature of some surfaces may
increase when the chair is exposed to
external heat sources as sunlight.
Do not install, maintain or operate your wheelchair without reading
all warnings and this entire user’s manual.
Always keep this manual in connection with your wheelchair.
NOTICE TO RIDER—WARNING
Do not use your wheelchair on stairs or escalators. Do not lift or move the
wheelchair by any of its removable parts.
The wheelchair should be turned off prior to entering or exiting the
wheelchair.
The wheelchair may come to a sudden stop at any time during operation.
Do not operate the wheelchair if it is behaving abnormally or erratically.
Do not operate the wheelchair with low batteries, to minimize risk of
becoming stranded.
Don’t use the wheelchair if your weight exceed the maximum user weight
written in the specification of this user manual.
Do not carry passengers on the wheelchair independently of the age of the
passenger.
PINCH HAZARDS – WARNING
Make sure your feet do not “hang up” or get caught in the space between
the footrests. In general, make sure you have proper space in areas you will
travel through to minimize pinching or entrapment of body parts.
Do not use an escalator to move the wheelchair between floors. Serious
bodily injury may occur.
Do not lean over the top of the back upholstery to reach objects from behind
as this may cause the wheelchair to tip over.

Do not tip or wheel the wheelchair with wheel locks. Wheel locks are not
brakes.
Do not stand on the frame of the wheelchair.
Always use caution when transferring in or out of the wheelchair. Every
precaution should be taken to reduce the transfer distance. Also be certain
the wheel locks are engaged to prevent the wheels from moving.
Caution—Obstacles
Riding over curbs or obstacles can cause tipping and serious bodily
harm. If you have any doubt that you can safely cross any curb or
obstacle, ALWAYS ASK FOR HELP. Be aware of your riding skills and
personal limitations. Develop new driving skills only with the help of
a companion.
Caution—Anti-Tippers
Using anti-tippers substantially reduces your risk of falling over
backwards, which can cause serious injury. The Anti-Tippers will keep
you from falling over, but they will limit your ability to be pulled up
curbs and some other maneuvers. IT IS NOT POSSIBLE TO HAVE THIS
WHEELCHAIR WITHOUT ANTI TIPPERS.
The wheelchair is not designed for weight training and is unsafe for
use as a seat while weight training. Weight training from the

3.5 Drive profile
As default in the wheelchair they are saved some different drive
profile for the use indoor and outdoor.
Additional profiles should be the result of customization for the
individual user.
Use the button “PROFILE” of the joystick to change different types of
profiles: they are sorted from the more indoor one to the more
outdoor one.
For each profiles it is possible to change the speed.
INDOOR PROFILES
When these profiles are activated most of the parameters of the
wheelchair are cut off. For example the maximum speed and the
acceleration are limited.
In this way the handling is really improved and there is more margin
for mistake on the lever of the joystick.
In this way it is comfortable to use the wheelchair in indoor
environments.
OUTDOOR PROFILES
When these profiles are activated most of the parameters of the
wheelchair are at the maximum value. For example the maximum
speed and the acceleration are not limited.
In this way it is comfortable to use the wheelchair in outdoor
environments.
However remember that the wheelchair EVO3 was designed for
use mostly in indoor environments.

www.neatech.it
31
DEFAULT POSITION
Default position mean a safe position for the seat system of the
wheelchair:
o Height of the seat = 0 cm
o Angle of seat = 0°
o Angle of legrest = 90°
o Angle of backrest = 90°
Obstacle climbing
When facing with an obstacle it is recommended to set the
position of the seat in the “default position”.
In order to riding over higher obstacles it is strongly
recommended to take a run up of almost 500 mm when
facing the obstacle first with castors.
Dealing with uphill
When facing an uphill road it is recommended to set the
position of the seat in the “default position”.
In order to best come over an uphill it is strongly
recommended to use an outdoor profile at maximum speed
with the wheelchair facing forward.
WARNING
Stopping and starting the chair while moving
up an incline makes the wheelchair more
difficult to control
www.neatech.it
32
Dealing with downhill
When facing a downhill road it is recommended to set the
position of the seat in the “default position”.
In order to best come over a downhill it is strongly
recommended to use an indoor profile at minimum speed
with the wheelchair facing forward.
WARNING
Don’t drive up or down slopes with a gradient
than indicated in section 5.4.
WARNING
Don’t drive up or down ramps that are not
equipped with proper edge protection to
prevent the wheelchair from falling down.
WARNING
Don’t drive down or up a hazardous incline if
the surface is covered with snow, ice or the
surface is uneven.
Driving on side slopes
When facing with side slopes, always drive the wheelchair with great
caution and at minimum speed
www.neatech.it
33
Turning with the wheelchair
Don’t turn with the wheelchair at high speed.
Driving in dark environments
Driving in dark environments can only be done if the wheelchair has
functioning lights
DRIVE WITH SEAT SYSTEM NOT IN DEFAULT
POSITION
Operating seat lift, tilt, backrest recline and
legrest elevation may change the center of
gravity and increase the risk of tipping
over.
Always drive in low speed and only use
these functions on level surface.
Safety belt
Evo3 wheelchair has the predisposition for a pelvic belt, that can be
purchased as an accessory.
Pelvic belt is only designed to position the user and not for any
protection in case of accident
www.neatech.it
34
Transfer into and out the wheelchair
Before entering or leaving the wheelchair turn it OFF.
Users transfer is recommended with the assistance of an attendant.
Don’t use the joystick as a hanrhold or point of support.
Don’t use footrests or armrests as support.
www.neatech.it
35
4.3 Manual brake release lever
In case of necessity it is possible to manually move the wheelchair.
First of all you have to turn off the wheelchair acting on the specific
button of the joystick, see Figure 20.
Then you can act on the release lever shown in Figure 21 and Figure
22.
When the brakes are released, it is not be possible to drive the
wheelchair.
Figure 21
Figure 22
WARNING
When the brakes are released never use
the wheelchair on a slope or a wet
surface.
Don’t operate the brake release without
the presence of an assistant
www.neatech.it
36
4.4 Powered function
Depending on the configuration of your own EVO3 some of this
function should be not available or different.
WARNING
Operating these functions changes the
center of gravity and increases the risk of
tipping over.
Always drive in low speed and only use
these functions on horizontal plane.
4.4.1 Seat lift
Figure 23
Figure 24
A maximum lift of 30 cm allows the user to have more independence.
www.neatech.it
37
4.4.2 Seat tilt
Adjusting the tilt of the
wheelchair (45°)
causes a better
distribution of
pressure on the body
of the user.
This helps to reduce
the incidence of all
problems due to
punctual localization
of loads.
Figure 25
Moreover tilting helps
you to avoid retention
of fluids in the lower
leg, make it easier to
sit on the wheelchair.
Figure 26
www.neatech.it
38
4.4.3 Backrest biomechanical recline
Figure 27
Figure 28
Powered reclining of the backrest (range 90°-170°) helps to improve
the posture. It is also useful to facilitate personal care. To best fit
physiological movement as the backrest recline, it also slides down.
The point of rotation of the backrest can’t coincide with the human’s
anatomical point of rotation of the back. The biomechanical reclining
is the best way to solve this and make the backrest and the headrest
to remain in the same position in relation to the back.
www.neatech.it
39
4.4.4 Legrest biomechanical elevation
A central
mounted legrest
takes up less
space than
separated legrest
making it easier
to move with the
wheelchair.
In this way even
lateral transfer
will be easier.
Figure 29
Figure 30
www.neatech.it
40
The knee that is
the point of
rotation of the
lower leg can’t
coincide with the
point of rotation
for the elevation
of the footrest.
EVO3 legrest has
an innovative
way to
compensate this
and assure that
the knee and the
thighs remain
firmly on the
wheelchair.
4.5 Battery charging
To recharge the batteries use only the provided charger or one
recommended by Neatech.it. The manufacturer is not responsible
for damage to person or property resulting from the use of nonoriginal product.
For a list of recommended charger please contact your vendor.

Connect the power cord to a power supply 230 V.

Connect the cable to the joystick as shown in Figure 31 and
Figure 32.
Figure 31

Figure 32
When batteries are loaded unplug the power cord and the
battery cable.
Battery charging should be done in well
ventilated environments. Never charge in
bathroom or wet room.
When the charger is connected it is not
possible to drive the wheelchair
www.neatech.it
41
Each battery is subject to a normal “self-discharge”, so batteries that
are not used for long time will discharge by itself.
Charging time is influenced by multiple factors such as remaining
battery power, battery state of aging and temperature. However the
approximate charging time is about 7-9 hours. If the charge duration
was reduced (about 1 hour), that is a sign of failure: contact the
vendor for a possible replacement of batteries.
Don’t use the wheelchair during the charge.
SHOCK HAZARD
Check if charger data sheet matches with
the network power (voltage, frequency).
Only use the charger supplied with the
wheelchair.
RELEASE DANGER
Any impact to the batteries could cause a
loss of fluids. Pay attention
ENVIRONMENTAL HAZARD
It is recommended to properly recycle used
batteries. Contact your local agency for
waste disposal for more information.
www.neatech.it
42
4.6 Use as seat in motor vehicle
Hooks for local travel (four-point tie-down)
The wheelchair was tested when used as a front-facing seat in a
motor vehicle, meeting the requirements of ISO 7176-19
The way of access to the motor vehicle and
handling within it is influenced by the size
of the wheelchair.
It is recommended to use the pelvic seat belt along the front of the
pelvic area, so that the angle of the belt is between 30° and 75° from
the horizontal, as shown in Figure 33; a greater angle, always in the
expected range, is preferable.
Figure 33
www.neatech.it
43
You should keep your seat belts as tight as possible to the body, but
without affecting the comfort
Make sure that the belts are not twisted during use.
It is recommended to use both the pelvic belt and the shoulder belt
to reduce the possibility of impact of the head and chest with vehicle
components.
Figure 34
Remove and assure inside the vehicle any not essential accessory
from the wheelchair in order to reduce the potential risk of injury.
If the wheelchair has been involved in some type of collision
between vehicles, it must be tested by the manufacturer before reuse.
Don’t make any alteration or tampering on point of safety or
structural parts.
www.neatech.it
44
Use extreme care when positioning the wheelchair, so that the
release button of the seat belt can not be pressed by its components
in case of impact.
The hooks that can be used with the wheelchair are “Four-Point TieDown” type. The wheelchair will be hooked up inside the motor
vehicle in 4 points: 2 front and 2 rear, as shown in Figure 35.
Figure 35
Don’t use any postural systems in a motor
vehicle unless they are conform to
ISO 7176-19.
